Mikako Satsukitane

Mikako Satsukitane (五月田根 美香子) is one of Tomoki Sakurai's friends as well as the Student Council President at his school.

Personality
Mikako is well known for her aggressiveness towards Tomoki, and she frequently torments him. She comes up with very perverted things to get him to do what she wants (eg. The snowball fight) Mikako made this event to get the boys to do whatever she wanted.

Mikako is very obsessed with violence. She took Astraea as her student and tried to teach her how to eliminate Tomoki. She is also very sadistic.

On rare occasions, Mikako has shown concern and emotional understanding of Ikaros, like when she orders Ikaros to drop Tomoki into the sea with the intention of Ikaros revealing her feelings to Tomoki.

Appearance
Mikako is a tall, well-endowed young woman. She has long, purple hair with two ribbons tied to both of her side burns. Mikako has squint-y dark-purple eyes and maintains a constant, sadistic grin. Her measurements are: 83-56-80. Her height is 164 cm, and she weighs 46 kilograms (101.4 lbs). She is considered a beautiful young woman by many.

Background
Mikako is an upperclassman to Tomoki and Sohara Mitsuki and the president of the Sorami Academy Student Council. She is Eishirou's childhood friend, whom she refers to as "Ei-kun," and the heiress of a Yakuza family. Mikako is manipulative, a genius intellectual, cunning, highly intelligent and sadistic, usually towards Tomoki. In the manga, she is forced to take supplementary lessons due to "failing in morals".

She is equal to Sugata in combat. Nymph states that she has a grip strength of 400 kg. She is extremely lucky. Sugata mentioned that Mikako once struck gold and found oil simply by digging a hole.

She is the chief mastermind of many schemes in the manga, and Sugata normally enlists the help of Tomoki (and occasionally some others) by persuading him to shut down her plans. Tomoki is the target of many of her schemes, serving to put him in undesirable situations and humiliating him, which suggests she sees him as a toy for her personal entertainment.

In the second movie (Eternal My Master), she demonstrates some supernatural powers when she reads Ikaros's mind, hinting her to have a connection to Synapse.

Plot
She first appears during Sugata's glider test at the school. After Tomoki requests her to talk down Sugata, she reveals that she is planning to profit from multiple life insurance bought out in his name.

She later holds Sugata captive, resulting in him not going with Tomoki to witness the void in the sky.

She visits Suguta at his campsite along with everyone else.

Mikako holds a snowball battle.

She later holds a festival with a large reward.
